Relative Humidity Formula
Magnus Formula
RH = 100 × e^(17.625×T_d/(243.04+T_d)) / e^(17.625×T/(243.04+T))
Where:
- • RH = relative humidity (%)
- • T = air temperature (°C)
- • T_d = dew point temperature (°C)
Interpretation
- • 0-30%: Very dry
- • 30-50%: Comfortable
- • 50-70%: Moderate
- • 70-100%: High humidity
